eNod4* is an analog data processing unit evaluated as a part of a non-automatic weighing instrument (NAWI) with applicative software -T or an automatic weighing instrument (AWI) like an automatic gravimetric filling instrument with


applicative software -D or a catchweigher with applicative software -C. This instrument is not intended for direct sales to the public. It is suitable for conditioning OIML R60 certified strain gauges load cell(s) with analog output. Legal for trade mode has to be activated internally in order to respect metrological requirements. All the functionalities will be conformed to the essential requirements for certified weighing instruments. Sealing will be material on the eNod4 housing and load cell connections. If a junction box is used it will have to be sealed too. eNod4 is fitted with a software sealing for metrological parameters and once activated, is composed of an event counter and a CRC value of specific and adjustment parameters. These values shall be marked on the terminal device connected after the last official verification when putting in service the instrument. Any mismatch between the displayed values on the terminal and those marked will signify a broken sealing. eNod4 is fitted with a data storage device (DSD) so called alibi memory. Any weighing result (or checkweigher result with applicative software -C, or dosing result with applicative software -D) is stored internally and can be recalled on demand. 130816 records can be stored permanently at maximum. Any record is identified by a unique 32-bit long number. This identifier is incremented each time a weighing result is stored and transmitted. The minimum time between two DSD recording operations is 50ms. * legal for trade use does not apply to software applicative for beltweigher (-B) and weigh feeder (-F)

4.1.2 Prevent Electromagnetic disturbances

Observe these basic rules to guard against Electromagnetic disturbances.

Rule 1: Large area grounding contact

When installing the devices, make sure that the surfaces of inactive metal parts are properly bonded to chassis ground (see following sections).

Bond all inactive metal parts to chassis ground, ensuring large area and low-impedance contact (large cross-sections).

When using screw connections on varnished or anodized metal parts, support contact with special contact washers or remove the protective insulating finish on the points of contact.

Wherever possible, avoid the use of aluminium parts for ground bonding. Aluminium oxidizes very easily and is therefore less suitable for ground bonding.

Provide a central connection between chassis ground and the ground/protective conductor system.

Rule 2: Proper cable routing

Organize your wiring system into cable groups (high-voltage/power supply/signal/measurement/data cables).

Always route high-voltage and data cables in separate ducts or in separate bundles.

Install the measurement cables as close as possible to grounded surfaces (e.g. supporting beans, metal rails, steel cabinet walls).

Rule 3: Fixing the cable shielding

Ensure proper fixation of the cable shielding.

Always use shielded data cables. Always connect both ends of the data cable shielding to ground on a large area.

Keep unshielded cable ends as short as possible.

Always use metal/metalized connector housings only for shielded data cables.

Shields of load cells must be connected to the pin ‘Shield’ of the load cell connector of the eNod4 or, in case of junction box, directly on the body of this one.

Rule 4: Special EMC measures

For cabinet or enclosure lighting in the immediate range of your controller, use incandescent lamps or interference suppressed fluorescent lamps.

Rule 5: Homogeneous reference potential

Create a homogeneous reference potential and ground all electrical equipment.

Use sufficiently dimensioned equipotential bonding conductors if potential differences exist or are expected between your system components.

Equipotential bonding is absolutely mandatory for applications in hazardous areas.


4.2 Power supply connection

On the front panel a green light ‘PWR’, (D7) indicates if power is connected.

4.3 Load-cell wiring

4 wires load-cell: jumpers in place (by default at delivery). 6 wires load-cell: jumpers removed

4.4 IO+ version An analog board in current and voltage might be used with eNod4 to provide IO+ version. This has to be requested when ordering eNod4 product. The analog output is both current and voltage galvanically isolated at 1000V. Voltage output might be set either 0-5V or 0-10V, and the current output to 4-20mA, 0-24mA, 0-20mA or 4-20mA alarm 3.6mA. It is software setting and both output (current and voltage) might separately be enable.

4.6.2 Excitation trimming procedure

For load cells with matched outputs, shortcut the potentiometers by soldering bridges J1, J2, J3, J4. First adjustment with reference weight:

1. Turn the potentiometers fully clockwise for each load cell so that the potentiometer resistance is as low as possible.

2. Lay your reference weight at one corner of your weighing system and note the result of the weighing indicator. Repeat this operation for each corner.

3. Spot the corner with the lowest output. Load successively each corner with the same reference weight and adjust at each step the potentiometer to match the lowest output corner value.

4. The load cells outputs are now matched. Then proceed to normal zero and gain adjustment of the weighing indicator.

4.6.3 Spring terminal connections

Use a screwdriver with a maximum blade width of 3 mm. 1. Press the black button with the screwdriver. 2. Stick the wire end into the relevant opening. 3. Release the pressure on the screwdriver. 4. Pull slightly the cable to check it is held tight.

6 CALIBRATION AND SCALE ADJUSTMENT eNod4 is factory calibrated to deliver 500 000 counts for 2mV/V with a load cell on the A3 input connector. Initial calibration can be modified for a better adjustment to the usage or because of characteristics of the sensor. To achieve these various types of adjustments the following options and procedures are available:

physical calibration theoretical calibration scale adjustment coefficient gravity correction

6.1 Physical calibration Physical calibration is done by applying to the sensor from 1 up to 3 known references.

6.2 Theoretical calibration The theoretical calibration allows defining eNod4 user span without using calibration reference. The information needed to achieve the procedure is the sensor sensitivity and its rated capacity. For example, a 15kg load cell with sensitivity equal to 1.870 mV/V at 15kg; put sensor maximum capacity 15 000 and sensor sensitivity 1,870.

6.3 Scale adjustment coefficient Initial calibration value can be modified with a scale adjustment coefficient. This coefficient has maximum and minimum values.

6.4 Gravity correction When eNod4 is used to condition a weighing sensor, it can be necessary to adjust measurement if the place of measurement is different from the place where eNod4 was calibrated. eNod4 automatically adapts its span by storing into its non-volatile memory these 2 parameters: ‘Calibration place g value’ and ‘Place of use g value’. Initial values for these coefficients are identical; they correspond to the g value of a calibration place located in ANNEMASSE FRANCE.

6.5 Scale interval The scale interval is the difference between 2 consecutives indications. Possible values are: 1, 2, 5, 10, 20, 50, and 100. Modification of scale interval is taking into account after a new calibration.

When using eNod4 for legal for trade purpose, it is imperatively required to activate the legal for trade switch

BEFORE any calibration procedure (cf § legal for trade switch). !


7 FILTERS There are four available filtering levels which can be associated:

filtering related to the A/D conversion rate including rejection of the mains frequency (50 or 60 Hz) harmonics.

low-pass Bessel filter notch filter self-adaptive filter

7.1 Filtering related to the A/D conversion rate The signal resolution is related to the conversion rate. The conversion rate might be chosen as low as possible, particularly for static applications. For dynamic applications, a compromise must be found between the measurement rate and the low-pass filter cut-off frequency. The eNodView software can be used to determine appropriate filter values. Choose a measurement rate that rejects the mains frequency harmonics according to the place of use, 50 or 60Hz.

7.2 Bessel low pass filter A low-pass digital filter can be applied as an output of the A/D converter. The filter orders (available values are 2, 3 or 4) and cut-off frequency are adjustable. eNodView software can be used to determine appropriate filter values.

7.3 Notch filter A notch filter might be applied as an output of the low-pass filter (if used) or the A/D converter. It allows attenuating the frequencies within a band defined by high and low cut-off frequencies. The eNodView software can be used to determine appropriate filter values.

7.4 Self-adaptive filter This filter can be set in cascade after previous filters. It is particularly efficient for static measurements but avoid using it in dynamic or dosing processes. The aim of this filter is to eliminate erratic measurements and to average consistent measurements.


8 MEASUREMENT AND STATUS The eNod4 transmits measure after signal and data processing through different protocols available. The accessible variables are:

8.1 Gross measurement The ‘gross measurement’ stands for the digital value after measurement scaling. It is affected by all the ‘zero’ functions (power-up zero, zero tracking and zero requests). Zero request value can be saved in non-volatile memory (option).

8.2 Net measurement The ‘net measurement’ stands for the digital value after measurement scaling and tare subtraction.

8.3 Tare value The ‘tare value’ stores the calibrated value that is subtracted from the ‘gross measurement’ so as to give the ‘net measurement’. This value can be saved in non-volatile memory (option).

8.4 Factory calibrated points The ‘factory calibrated points” contains the measurement value without the user calibration layer. It is directly linked to the analog input voltage.

8.5 Logical IN/OUT level The ‘logical IN/OUT level’ allows reading any time eNod4 logical inputs and outputs level.

8.6 Preset Tare value A previous calculated tare can be restored using this variable. This value can be saved in non-volatile memory (option).

8.7 Measurement status The measurement status contains information on eNod4 measurement parameters.

8.8 Weighing diagnosis

8.8.1 Global weighing diagnosis An internal alarm flag reflects the integrity of the whole measurement chain. It’s used to set logical output active or optional analog output in an error mode in order to warn about any defection on the measurement chain (defective measurement). This variable is set active when at least one of the followings conditions occurs:

- sensor input control result out of tolerances - sensor input control command in progress - sensor input control command failed (timeout) - sensor input reference command in progress - gross meas. < (- max capacity) - gross meas. > (max capacity) - analog signal out of the A/D converter input range - EEPROM failure

This internal alarm flag is featured with adjustable specific de-bounced time and minimal activation time.

8.8.2 Sensor input control eNod4 features a weighing diagnosis system allowing to check the integrity of analog sensor input by electrically simulating a load, resulting to a simulated weight value. This diagnostic system can be used together with the others defects detection systems in order to achieve overall integrity check of the measurement chain. This system involves two phases initiated by the user:

- The first, just after user calibration, allows taking a simulated reference weight value when the measuring chain integrity is OK.

- The second, when the user wants to check the integrity of the system, allows to make the difference between a new simulated weight value and the reference. Then this difference can be compared with a dedicated maximum tolerance value.


9 LOGICAL INPUTS Each input can work individually in either positive or negative logic. A holding time (de-bounced time) attached to all inputs can be configured.

9.1 Inputs assignment Inputs can be assigned individually to one of the following functions:

none tare zero send measurement measurement window cancel tare sensor input control

Function Functioning mode

transmitter

None

Tare

Cancel tare

Zero

Measure transmission (SCMBus/Fast SCMBus only)

Continuous measure transmission (SCMBus/Fast SCMBus only)

Sensor input control

9.2 Inputs function description

9.2.1 None Inputs have no effect.

9.2.2 Tare Each input can be assigned to the tare function. Depending on the chosen logic (positive or negative) for the corresponding input, tare is triggered by a falling or rising edge.

9.2.3 Cancel Tare Depending on the chosen logic (positive or negative), the tare is cancelled by a falling or rising edge of the corresponding input.

9.2.4 Zero Each input can be assigned to the zero function. Depending on the chosen logic (positive or negative) for the corresponding input, zero acquisition is triggered by a falling or rising edge. A new zero is acquired only if its value is within a range 10% of maximum capacity or 2% if eNod4 is in legal for trade functioning mode. This new value is the useful zero value, a reset cancels it.

9.2.5 Measure transmission (SCMBus/fast SCMBus only) The request can apply to:

gross measurement net measurement factory calibrated points

A single measurement is transmitted per rising or falling edge (depending on the configured logic) on the input signal.


9.2.6 Continuous measure transmission (SCMBus/fast SCMBus only)

The request can apply to: gross measurement net measurement factory calibrated points

While the input is kept at the right level, a series of measurements are transmitted at the period defined by the ‘sampling period’ setting. If the 2 inputs are assigned to this function, only input 2 is operating.

9.2.7 Sensor input control The assignment of logical input to sensor input control function allows performing special procedure to diagnose load cell sensor input. Beforehand, user must acquire reference value of the load cell input by sending 'Sensor input control reference' specific command (e.g. after the device is calibrated). Note: Load cell sensor input control must be realized if no process cycle is in progress.


10 LOGICAL OUTPUTS Each output can be individually set to positive or negative logic.

10.1 Outputs assignment Outputs can be assigned individually to one of the following functions:

Function Functioning mode

Transmitter

None

Set point

Motion

Defective measurement

Input image

Level on request

10.2 Description

10.2.1 None The output has no function.

10.2.2 Set point The outputs can be assigned to configurable set points. Output 1 is assigned to set point 1, output 2 to set point 2 and so on. Set points can be assigned to gross measurement or net measurement and are defined by a high value, a low value and a functioning mode. Two functioning modes are possible:

Hysteresis Window

10.2.3 Motion:

The outputs can be assigned to measurements stability criteria.

10.2.4 Defective measurement: The output level is set when the internal alarm flag described in “Weighing diagnosis” § in the MEASUREMENT AND STATUS § is activated. This allows to warn about defection of the measurement chain.


10.2.5 Input image: Outputs can be assigned to copying inputs state, either using the same logic or inverting the input state (negative logic). Outputs 1 and 3 can be assigned to input 1 and outputs 2 and 4 to input 2.

10.2.6 Level on request: Activation of outputs is triggered by master requests.

10.3 Analog output (IO+ version) An optional analog board in current and voltage might be used with eNod4 to provide IO+ version. This must be asked when ordering eNod4 product. Voltage output might be set either 0-5V or 0-10V, and the current output to 4-20mA, 0-24mA, 0-20mA or 4-20mA with alarm at 3.6mA. Both output (current and voltage) might separately be enable. Settings are effective after eNod4 reset. Analog output affectation function is common to both current and voltage output and might be assigned to followings:

None: analog outputs have no function. Gross measurement: analog outputs can be assigned to gross measurement copy. Maximal level value is

related to Maximum Capacity parameter and works in mono-quadrant functioning. Bi-quadrant option can only be applied to gross measurement copy. When this option is activated, the lowest value of current and voltage levels corresponds to -MC and the highest value to +MC.

Net measurement: analog outputs can be assigned to net measurement copy. Maximal value is related to Maximum Capacity parameter and works in mono-quadrant functioning only. The highest value of current and voltage levels corresponds to +MC in only one quadrant.

Level on request: analog outputs are driven by master requests through the external value to control analog output variable (in 0.01% of the full scale of current or voltage analog outputs).

When analog output is assigned to “Gross measurement” or “Net measurement” its value jumps to a special error value when the internal alarm flag described in “Weighing diagnosis” § in the MEASUREMENT AND STATUS § is activated. This allows to warn about defection of the measurement chain.

Result of sensor(s) input control test expressed in 1/10 of user weight unit. Its value is automatically determined and stored after executing the sensor input control command. This test result represents the weight difference between the reference value and the current test value.

Result max. tolerance 0.0 – 6553.5

The Sensor input control result variable is compared with the Sensor input control result max. Tolerance parameter which is expressed in 1/10 of user weight unit and has a default value of 30. If the sensor input control result value is greater than or equal to “Sensor input control result max. Tolerance” then an error is reported

Sensor input control command will cause eNod4 to handle special test on sensor input and to deliver a test result. This command must not be realized when any process cycle that use weight is in progress.

Sensor input reference command will cause eNod4 to handle special sequence to acquire sensor input control reference value of the load cell sensor input. This command must be performed before using the Sensor input control command and each time the weight measurement chain (sensor, connection, calibration) is modified. This command must not be realized when any process cycle that use weight is in progress.
